Abstract

The present application discloses a display panel comprising at least two display regions comprising a first display region and a second display region; the first display region comprises a first light guide having a structure which defines a first light emission angle relative to a light emission surface of the first display region; the second display region comprises a second light guide having a structure which defines a second light emission angle relative to a light emission surface of the second display region.

First claim

1 . A display panel, comprising:
at least two display regions comprising a first display region and a second display region; the first display region comprises a first light guide having a structure which defines a first light emission angle relative to a light emission surface of the first display region; the second display region comprises a second light guide having a structure which defines a second light emission angle relative to a light emission surface of the second display region.

2 . The display panel of claim 1 , wherein a projection of the first light emission angle in plan view of the display panel defines a first orientation of the first light emission angle; a projection of the second light emission angle in plan view of the display panel defines a second orientation of the second light emission angle different from the first orientation.

3 . The display panel of claim 1 , wherein the first display region and the second display region are integral in one display panel.

4 . The display panel of claim 1 , further comprising at least two signal input terminals, each of which connected to one of the at least two display regions for receiving image input signal into the one of the at least two display regions.

5 . The display panel of claim 1 , further comprising a main display region.

6 . (canceled)

7 . (canceled)

8 . The display panel of claim 5 , wherein the main display region and the at least two display regions are integral in one display panel.

9 . The display panel of claim 5 , wherein the main display region is a rectangular region, the at least two regions are four trapezoid regions, a short base of each of the four trapezoid regions abutting one side of the rectangular region, each side of each of the four trapezoid regions abutting a side of a neighboring trapezoid region, four long bases of the four trapezoid regions form the outer edge of a display region of the display panel.

10 . The display panel of claim 5 , wherein the display panel comprises a central signal input terminal connected to the main display region for receiving image input signal into the main display region, and at least two signal input terminals, each of which connected to one of the at least two display regions for receiving image input signal into the one of the at least two display regions.

11 . The display panel of claim 5 , a pixel density in the main display region is smaller than a pixel density in any one of the at least two display regions.

12 . The display panel of claim 1 , wherein at least one of the first light guide and the second light guide is a grating layer.

13 . The display panel of claim 12 , wherein the grating layer comprises a plate grating.

14 . The display panel of claim 13 , wherein the plate grating comprises a plurality of inclined parallel non-transparent plates having an inclined direction relative to a light emitting surface of a display region which defines a light emission angle.

15 . The display panel of claim 12 , wherein the grating layer comprises a lens grating.

16 . The display panel of claim 15 , wherein the lens grating comprises a plurality of strips each of which having a convex surface, the lens grating having a diffraction direction relative to a light emitting surface of a display region which defines a light emission angle.

17 . The display panel of claim 12 , wherein the grating layer comprises a liquid crystal grating.

18 . The display panel of claim 17 , wherein the liquid crystal grating comprises an electrode layer and a liquid crystal layer, wherein the electrode layer has an electrode pattern for applying an electric field across the liquid crystal layer to alter the optical properties of the liquid crystal layer such that the liquid crystal grating is induced by the electrical field, the liquid crystal grating having a diffraction direction relative to a light emitting surface of a display region which defines a light emission angle.

19 . (canceled)

20 . (canceled)

21 . (canceled)

22 . The display panel of claim 1 , wherein the display panel comprises a display orientation controller for independently control display orientation in the at least two display regions.

23 . The display panel of claim 22 , wherein the display orientation controller comprises a plurality of field programmable gate arrays, each of which corresponds to the main display region or one of the at least two display regions.

24 . The display panel of claim 1 , further comprising a touch control layer for simultaneously detecting touch signals in the at least two display regions.

25 . A display apparatus comprising a display panel of claim 1 .
